This powerful Internet tool set was once only available to computer
specialists. Now, because of Java, anyone can access them.

Unfortunately, unlike most of my Java programs, this one must be downloaded and
run as an application in order to work. The example shown below will not
function while online (unless you have a very special browser).

Here are the included Internet tools:

Service Name

TCP/IP Port number

Description

Whois

43

Use the Internet's own internal record system to find out who owns any domain,
and who is using a particular address. You can use this tool to find the name
and address of someone sending you spam e-mail.

Finger

79

Find out who is logged onto a particular system.

Domain Name Server

53

Find the address for a host name, find your own machine's address. This can be
used to discover whether a particular name is in use.

Time

13

Access an atomic clock to get the time of day.

Here is what the application looks like. Remember, unless your browser is set
up in a very peculiar way, you won't be able to actually use the functions
until you download the application
